The height of the washington monument is measured to be 170 m on a day when the temperature is 30.0°c. what will its height be in meters on a day when the temperature falls to −16.0°c? although the monument is made of limestone, assume that its thermal coefficient of expansion is the same as marble's.

Answers

This is a case of linear expansion. The general expression of linear expansion is given by:

ΔL = αLΔT, ΔL = change in length or height, α = coefficient of linear thermal expansion, ΔT = Change in temperature.
In the current case;
α = 2.5*10^-6 /°C (for Marble)
L = 170 m at 30.0°C
ΔT = 30 - (-16) = 46°C

Substituting;
ΔL = 2.5*10^-6 *170*46 = 0.01955 m

Height at -16°C = 170 - 0.01955 = 169.98 m

Answers

Heat within the earth generates convection currents in the mantle. Convection currents represent the circular motion of molten rocks in the mantle driven by heat from the core. This circular motion is what drives the plates and creates the theory of plate tectonics which states that the earth crust is divided into plates that float on the semi-molten mantle below.

When a front wheel drops off the roadway you should?

Answers

braking and returning suddenly to the roadway

When a front wheel drops off the roadway, stay calm, maintain a firm grip on the steering wheel, slow down gradually, and carefully steer back onto the road while checking for traffic.

When a front wheel drops off the roadway while you are driving, there are several steps you should follow to safely regain control:

Stay calm: Avoid any sudden movements or panicking, which can worsen the situation.

Hold the steering wheel: Keep a firm grip on the steering wheel to maintain control of the vehicle.

Decelerate gradually: Slowly lift your foot off the accelerator to decrease speed, but do not brake suddenly as this can cause further loss of control.

Slowly steer back: Gradually steer the vehicle back onto the roadway once you have slowed down sufficiently.

Check for traffic: Always ensure it is safe to merge back onto the road by checking for other vehicles.

By following these steps, you can safely recover from your front wheel dropping off the roadway and minimize the risk of an accident.

A 100 kg bag of sand has a weight on 100 N. When dropped its acceleration is what?

Answers

100N describes the weight of the sandbag, while 100kg is the mass of the sandbag.

To calculate acceleration, divide your weight by the mass, thus the accleration is:

[tex]100N/100kg = 1(m/s^2)[/tex]

Answer:

Gravity.

Explanation:

If you are holding the bag of sand, the only acceleration in the system is gravity, because is a vertical movement. So, [tex]a = 9.81 \frac{m}{s^{2} }[/tex]

We are assuming that is vertical movement because is say ''dropped'', which is a term used in Free-fall models, where acceleration is constant.

The molar enthalpy of fusion for water is 6.008 kj/mol. what quantity of energy is released when 253g of liquid water freezes? (molar mass of water is 18.02 g/mol)

Answers

During freezing, energy is released by the mass of water without change in temperature. Such energy will also be required if the same mass of water has to be melted.

Then,

Number of moles = mass/molar mass = 253/18.02 =14.04 moles

Energy released = moles*molar enthalpy of fusion = 14.04*6.008 = 84.35 kJ

What is the wavelength (angstroms) of a photon that has an energy of 4.38 x 10-18 j?

Answers

The relationship between energy and frequency of a photon is given by
[tex]E=hf[/tex]
where E is the energy, h is the Planck constant and f is the photon frequency. By re-arranging the equation and using the photon energy, we can calculate its frequency:
[tex]f= \frac{E}{h}= \frac{4.38 \cdot 10^{-18} J}{6.6 \cdot 10^{-34}Js}=6.64 \cdot 10^{15} Hz [/tex]

Then we know that the photon travels at speed of light, c, so we can find its wavelength by using
[tex]\lambda= \frac{c}{f}= \frac{3 \cdot 10^8 m/s}{6.64 \cdot 10^{15}Hz}=4.52 \cdot 10^{-8} m [/tex]

And since 1 A (angstrom) corresponds to [tex]10^{-15} m[/tex], the wavelength expressed in angstroms is
[tex]\lambda= \frac{ 4.52 \cdot 10^{-8} m}{10^{-15} m/A} = 4.52 \cdot 10^7 A [/tex]

Answer: The relationship between energy and frequency of a photon is given by E = h*f.

E is the energy, h is planck constant and f is the frequency and f= c/λ.

But i want wavelength, so i write this equation as E= h*c/λ.

now

c=3.8[tex]*10^{8}[/tex]

E =4.38*[tex]10^{-18} [/tex] [tex]\frac{m^{2}*kg }{s^{2} }[/tex]

where i replaced joules for [tex]\frac{m^{2}*kg }{s^{2} }[/tex]

h = 6.62607004 *[tex]10^{-34}[/tex][tex]\frac{m^{2}*kg }{s }[/tex]

then λ = h*c/E = [tex]\frac{6.62607004 *10^{-34}*3.8*10^{8}m/s}{4.38*10^{-18} \frac{m^{2}*kg }{s^{2} }}[/tex] = 5.7*[tex]10^{-8}[/tex] m

But you want the solution in angstroms, so 1 meter is [tex]10^{10}[/tex] angstroms

so λ = 5.7*[tex]10^{2}[/tex] = 570 angstrom

Temperatures of four liquid substances are shown in the chart.

Which statement is best supported by the data in the chart?

A) Substance X will transfer thermal energy to substance Y mainly through radiation if they are mixed.
B) Substance Y will transfer thermal energy to substance Z through conduction if they are mixed.
C) Substance X will transfer thermal energy to substance W through radiation if they are placed near each other.
D) Substance W will transfer thermal energy to substance X through conduction if they are mixed.

Answers

For those of you taking the course on Edge, the right answer is D.

Answer: D) Substance W will transfer thermal energy to substance X through conduction if they are mixed.

Explanation: Thermal energy is the energy possessed by an object by virtue of its temperature. It is transferred from a hotter object to a colder object till both the bodies attain the same temperature.

Radiation occurs when thermal energy is transferred by electromagnetic waves. Conduction occurs when thermal energy is transferred when two objects are in direct contact.

Thus Substance W at a temperature of [tex]40^0C[/tex] will transfer thermal energy to substance X at a temperature of [tex]37^0C[/tex] through conduction if they are mixed as they are in direct contact.

The graph indicates what about the relationship between wavelength and frequency

Answers

We can't see the graph.
But is has to show that wavelength and frequency are inversely
proportional. In other words, their product is constant.
That's because their product is the speed of the wave.
If the graph doesn't show that, then the graph is wrong.

Wavelength and frequency of awave are in inverse proportion. Therefore, the graph showing as the frequency increases, wavelength decreases.

What is wavelength?

Wavelength of an electromagnetic wave is the distance between its two consecutive troughs or two consecutive crusts. Wavelength of a wave indicates how much distance it can cover.

Frequency of an electromagnetic wave is the number of cycles or waves get in one second. Thus its unit is s-1. Frequency of first last some radiations in the spectrum that are UV, gamma, x-ray etc are higher and they have shorter wavelength.

High frequency waves are more energetic whereas longer wavelength is associated with less energy. The relation between frequency v and wavelength lambda is written as follows:

[tex]v = \frac{c}{\lambda}[/tex]

Where c is the speed of light.

As per this relation frequency is inversely proportional to the wavelength. Hence they are in inverse relation.

Jake and brenda drove at a speed of 30 miles for one hour then they turned around and drove 45 miles per hour until they were back where they started what is the true or what is true about their average speed and average velocity

Answers

Their average speed is greater than their average velocity.

Answer:

Average speed is greater than average velocity. Average velocity is zero.

Explanation:

Average speed is calculated by:

[tex]\text{Average speed} =\frac{\text {Total Distance}}{\text{Total time taken}}[/tex]

Distance is the length of the total path traveled.

Average velocity is given by:

[tex]\text{Average velocity} =\frac{\text {Total Displacement}}{\text{Total time taken}}[/tex]

Displacement = final position - initial position.

Since, final position =initial position, Displacement = 0, therefore, average velocity = 0

It can be concluded that average velocity is zero and average speed is greater than average velocity.

If we start with 1.000 g of cobalt-60, 0.675 g will remain after 3.00 yr. this means that the of is _____

Answers

Cobalt-60 is undergoing a radioactivity decay.

The formula of the decay is n=N(1/2)∧(T/t).
Where N ⇒ original mass of cobalt
n ⇒ remaining mass of cobalt after 3 years
T ⇒ decaying period
t ⇒ half-life of cobalt.

So,
0.675 = 1 × 0.5∧(3/t)
log 0.675 = log 0.5∧(3/t)
3/t = log 0.675 ÷log 0.5
3/t= 0.567

t = 3÷0.567
= 5.290626524

the half-life of Cobalt-60 is 5.29 years.

Which is a characteristic that makes electromagnetic waves and water waves different

Answers

We know that a wave is a disturbance that transfers energy through matter or space There are two main types of waves: Mechanical and Electromagnetic. Water waves are mechanical. A mechanical wave is an oscillation of matter to transfers energy, but you always need a medium (substance such as: solid, liquid, gas, plasma) to transport it. The medium for water waves is, in fact, the water. For example, ripple in water is a surface wave. On the other hand, electromagnetic waves don't need a medium to transport, they can do it through the empty space. Then, this is the major characteristic that makes these two types of waves different.

Why is newton's first law of motion sometimes called the lae of inertia?

Answers

Newton's 1st law of motion states that an object at rest stays at rest and an object in uniform motion along a straight line stays in motion unless acted upon by an unbalanced force.
This law talks about the tendency of an object to resist any change in its state of rest or uniform motion, this is called Inertia. Thus Newton's 1st law of motion is also called the Law of Inertia

Final answer:

Newton's first law of motion, also known as the law of inertia, states that an object at rest remains at rest and an object in motion remains in motion unless acted upon by an external force.

Explanation:

Newton's first law of motion states that a body at rest remains at rest or, if in motion, remains in motion at a constant velocity unless acted on by a net external force. This law is also known as the law of inertia. Inertia is the tendency of an object at rest to remain at rest or, if moving, to remain in motion at constant velocity. Inertia is related to an object's mass.

A girl throws a rock horizontally, with a velocity of 10 m/s, from a bridge. it falls 20 m to the water below. how far does the rock travel horizontally before striking the water, assuming negligible air resistance?

Answers

Before you begin, you need to first figure out what your problem gives you and what you need to look for.
Given:
vix=10m/s
dy= 20m

What you are looking for is horizontal distance or dx.

The formula for vertical distance is:
[tex]dx=vi_{x}t[/tex]

Where:
dx= horizontal distance
vix= initial horizontal velocity
t=time

But when you look at your problem, you do not have time. Now for time, you need to use the formula:

[tex]t= \sqrt{ \frac{2dy}{g} } [/tex]

g in this equation is a constant. It is the acceleration due to gravity which has the value of 9.8m/s^2.

Now we first need to get time:
[tex]t= \sqrt{ \frac{2dy}{g} } [/tex]
[tex]t= \sqrt{ \frac{2(20m}{9.8m/s^{2}} } [/tex]
[tex]t= \sqrt{ 4.08163265} [/tex]
[tex]t=2.02s [/tex]

Now that you have time, all you need to do is insert that into our equation for horizontal distance.

[tex]dx=vi_{x}t[/tex]
[tex]dx=(10m/s)(2.02s)[/tex]
[tex]dx=20.20m[/tex]

The horizontal distance of the rock will be 20.20m.

Final answer:

The rock strikes the water after traveling approximately 20.3 meters horizontally. This is calculated using principles of physics related to projectile motion, with the separate vertical and horizontal movements taking place simultaneously and independently.

Explanation:

The physics problem you've described deals with the concept of projectile motion. In this scenario, the horizontal and vertical movements of the rock can be analyzed separately. The vertical displacement doesn't affect the horizontal one given the negligible air resistance.

First, let's find the time it takes for the rock to hit the water below. We can use the equation of motion, d = 0.5*g*t², where g is the acceleration due to gravity (9.8 m/s²), and d is the vertical displacement (20 m). Solving for t, we get approximately 2.03 seconds.

Then, to find the horizontal distance that the rock traveled, we use the formula for velocity (v = d/t), rearranged to solve for distance: d = v*t. Here, v is the initial velocity of the rock (10 m/s) and t is the previously calculated time (2.03 seconds). Completing the calculation, we find that the horizontal distance the rock travels before striking the water is approximately 20.3 meters.

What are solar and lunar eclipses?

Eclipses are of two types: Solar and Lunar eclipse. A solar eclipse occurs when the moon enters between the sun and the earth, which its shadow on the earth's surface.

A lunar eclipse occurs when the earth is moved between the sun and the moon and the Earth leaves its shadow on the moon. The tides form in seas because of the gravitational force of the moon.

The gravity of the moon makes the tides or waves in the seas or oceans. The full moon has more gravitation force and hence, larger tides are formed. The largest tides are also formed by solar and lunar eclipses.

When the sun is aligned with the moon during the eclipse, the sun is also pulling in the same direction resulting in the largest tides. The gravitational pull of the sun and moon increases the tides in ocean surfaces on Earth.

Thus, the largest tides occur at Full moon, solar and lunar eclipse. The correct options are B, E, and F.

a) speed
b) velocity
c) acceleration

Answers

think the answer should be C

Final answer:

As the roller coaster ascends the hill, it experiences a decrease in speed which affects its velocity, leading to what we describe as negative acceleration or deceleration.

Explanation:

When a roller coaster is traveling up a hill, it begins to slow down due to the force of gravity opposing its motion. This is a scenario of negative acceleration or deceleration.

Speed refers to how fast an object is moving without concerning the direction. In this case, the speed of the roller coaster decreases as it climbs the hill.

Velocity includes both the speed and direction of an object's motion. Here, the velocity also decreases as the speed decreases and the direction is upwards.

Acceleration refers to the rate of change of velocity. When the roller coaster slows down while moving up, it is undergoing negative acceleration or deceleration.
